Patent GB-1538428-A (GB)
Title: Food products
IPC: A21D15/00
Filed: 1975-03-26
Abstract: To produce packaged bakery products having improved storage time, the products are baked and cooled in a film packaging which forms an aseptic barrier and permits the escape of steam during baking. The packaged baked products are then hermetically sealed and pasteurised.   Baking is performed in such a manner that a temperature of at least 90 DEG C is reached in the interior of the bakery product for at least 30 minutes. The baking conditions should be selected so that a water activity of less than 0.95 is achieved in the baked product. To produce packaged, partly pre-baked bread, dough is baked at a temperature at which browning is avoided. The packaged, pre-baked products have a high storage stability and, compared with known products, are very stable with regard to attack by micro-organisms.

Abstract: 739,730. Photo-electric facsimile reproduction system. STANDARD TELEPHONES & CABLES, Ltd. Jan. 18, 1952 [Feb. 28, 1951], No. 13195/53. Divided out of 739,707. Class 40 (3). In an arrangement for the transmission of facsimile signals a ripple in the output due to alternating current excitation of the light source is eliminated by combining with the photo-cell output a voltage of the same magnitude and frequency but of opposite phase. As shown the light source EL is supplied from the secondary of the mains transformer 29 which also supplies a full-wave rectifier circuit 27 the output of which is smoothed and used to supply amplifying valve 14, 44, 45 and a photo-electric cell 11 receiving light from the object C to be copied. The unsmoothed output of the full wave rectifier fluctuating at double mains frequency as does light intensity is applied through a filter 70 which accepts double mains frequency and is then fed through a phase-shifting network 71, to the grid of a modulating valve 79. The phase and magnitude of the output are adjusted by the tappings of potentiometers 72 and 76 respectively. The anode of tube 79 is connected to the anode of photo-cell 10 so that the modulating components in the cell output are balanced out. A band rejection filter 86 is situated between the cell and the amplifier. The apparatus shown also incorporates an arrangement for compensating for variations of supply voltage. This arrangement forms the subject-matter of Specification 739,707.

Title: Method and apparatus for maintaining the point of impact of an electron beam for welding on the intended weld line
IPC: H01J37/304
Filed: 1971-05-05
Abstract: 1354575 Automatic control of electron welding beam position; automatic electric controller COMMISSARIAT A L'ENERGIE ATOMIQUE 5 May 1971 [5 May 1970] 13250/71 Headings G3N and G3R An electron beam 6 is maintained on a weld line 5 by detecting any difference between the electrons scattered on either side of the line and using such difference to alter the deflection of the beam. Scattered electrons are collected by tubes 10, 11 having apertures 12, 13 corresponding to the beam power and suitably biased to restrict their response to the required electrons. The tubes are connected to a differential amplifier 15 controlling deflecting coils 9 by an arrangement 14 in which the amplifier output (when above a threshold) enables one or the other of two AND gates (19, 20) Fig. 2, (not shown), according to polarity, to gate pulses from an oscillator (37) to a counter (21) in a digital to analogue converter. Initially, with the beam on the line the converter output voltage equals that of a reference (22') but if the line or beam deviates more electrons will be scattered to one side or the other and the converter output will be above or below the reference voltage. Comparison is made in a second differential amplifier (22) whose output is connected to the coils 9. The arrangement 14 also has a pair of trigger devices which reduce the output of the electron gun 7, 8 and may sound an alarm if the departure from the weld line exceeds prescribed limits.

Abstract: 704,176. Thermal switches. THORN ELECTRICAL INDUSTRIES, Ltd. June 3, 1952 [June 7, 1951], No. 13568/51. Class 38(5) [Also in Group XXXV] A glow-discharge starting switch for series-connected discharge tubes includes two pairs of switch electrodes in a common envelope 20 each pair consisting of one bimetallic electrode, and another which may or may not be bimetallic. When the switch 17 is closed, glow discharge is established between electrodes 18, 19 and the bimetals move towards their neighbours until the pairs 19, 22 and 18, 21 are closed. The filaments are then in series across the supply and are heated. The glow switch then opens and the tubes strike. The strips 21, 22 have extensions 21A, 22A, projecting beyond them, and if a fault interrupts the connection between the two first strips 18, 19 through the filaments of the tube, the discharge is maintained and 21A, 22A, move together after a delay and short-circuit the glow path, so preventing damage to the switch. In Fig. 3 (not shown) the strips 18, 19 are in the positions occupied by strips 21, 22 in Fig. 2 and the co-operating electrodes are fixed. In Fig. 4 (not shown) the strip 18 moves to engage, first its companion electrode, and then the fixed electrode of the other switch. The bimetal strips may alternatively carry contacts which first engage companion fixed electrodes and then slide on then to engage the other strip, Figs. 5, 6 (not shown). The fixed electrodes may carry rigid projecting strips which retard the bimetals, Fig. 7 (not shown).
